Application filed January 3,1811. Serial No. 600,432

To @ZZ whom it may concern:

Be it known that I, ELIHU N. KLEINBAUM, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented c'ertain new and useful Improvements in Pay-as-You- Enter Doors; and I do hereby declare the following tobe a,full, elear,-and exact description of the invention, such as-will en'- able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

The present inventionrelates', generally,

to improvements in pay as you enter doors, gateways, turn-stiles, and the like; and, the invention has reference, more particularly, to a construction of normally locked door or turn-stile which is released from its locked condition by the deposit of a coin, so as to permit the entrance of a person therethrough.

The invention has for its principal object to provide a pay-as-you-enter door or turn-stile which is of such a construction,

that it is maintained in a normally locked ing detailed description ofthe present in vention. Y V

Vith the various objects of the present invention in view, the said invention consists in the general arrangements and combinations of the devices and parts, as wellas in the details .of the construction of the same, all of which will be hereinafter more fully set forth, and then finally embodied in. the clauses of the claim which arev appendedto and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is an elevation of the novel con-- struction of pay-as-you-enter door or turn-stile and its automatic coin-controlled locking and releasing mechanism, the same being made according to and; embodying the principles of the present invention. Fig. 2

is a semi-diagrammatic detail View combining'therein vertical cross-sections of the automatic locking and releasing mechanism of the pay-as-you-enter door or turn-stile and the coin -controlled device connected therewith, together with the system of electrical wiring for operatively connecting the same, saidview being drawn upon an enlarged scale. Fig. 3 is a horizontal section taken below the door or turn-stile member and the floor-plate, looking in a downward direction. Fig. 4- is a large detail cross-section of a circuit-closing mechanism for operating said coin-controlled device, to release the coin from its operative relation therewith, whereby the main electrical circuit is broken, and the. lockingmechanism of the door or turn stile is returned to its normal locking condition; andFig. 5 is a transverse section of the same, taken on line 5-5 in said- Fig: 4. i a

Similar characters of reference are employed in all of theabove described views, to indicate corresponding parts.

Referring now to the several figures-of the drawings, the'reference-character l indicates a suitable frame or gateway .in which is located. the pay-as-you-enter door or turn-stile. Said pay-as-you-enter door or turn-stile may be constructed in various ways or styles. As shown in the accompanying drawings, the fpay-as-youenter door. or turn-stile comprises a vertical central, shaft 2, journaled at one end in a suitable bearing '3 which is connected with said frame 1, andin a suitable bearing-portion 4- of a floor-plate 5 Which is arranged beneath said door or turn-stile, and covers a floor-pit 6. The lower end of said shaft 2 is journaled in a thrust bearing block 7 which is secured upon the bottom of said floor-pit 6, and secured upon said shaft 2, in any suitable manner, are a plurality of radiatingdoor or stile-members 8, of any desirable form or construction. Secured upon said shaft 2, beneath said floor-plate 5, by means of a key 9, or any other suitable fastening means, is a lock-disk of wheel 10, which is provided in its circumferential portion with a plurality of bolt-receiving grooves or spaces 11, corresponding in numher and position to the said radiating door on stile-members 8 connected with and extending from the upper portion of said shaft 2. Secured upon said shaft 2, preferably beneath said lock-disk or wheel 10, by means of a key 12, or any other suitable fastening means, is a ratchet-wheel 13, the same being provided with suitably disposed teeth 14. The said thrust-bearing block 7 is provided with a suitably located and upwardly extending boss or block 15, provided with a stud-pin 16 upon which is pivotally mounted a pawl 17, said pawl being adapted to, engage said teeth 14 of said ratchet-wheel 13, whereby said pay-as-youenter door or turn-stile is permitted to be turned only in a proper direction. Said boss or block 15 is further provided with a lug 18 having a receiving socket for seating therein a spring-member 19, which bears against the pawl 17 and maintains the latter in its operative relation with said ratchetwheel 13. Secured within said floor-pit 6, in any desirable location and manner, are a pair of solenoid-coils 20, and further arrangedwithin said floor-pit 6, so as to be located opposite the free ends of said solenoid-coils 20, are pairs of standards 21 which areprovided with suitable bearing port-ions 22 for slidably supporting the armatures 23 of said solenoid-coils 20. The outer end of each armature 23 is formed to provide a locking bolt 24, provided with an anti-friction roller 24", the same being adapted to normally enter one of said boltreceiving grooves or spaces 11 of said lockdisk or wheel 10, and thereby engaging the latter so as to prevent the turning or revolving of the door or turn-stile until said locking-bolt is released or retracted from said engagement. Arranged about each of said armatures 23, between the bearing-portions 22 of said standards 21, is a springmember 25 which bears at one of its ends against one of said bearing-portions 22, and at its other end against a suitable stop secured to said armature, such as the transverse pin 26. The tension or pressure of said spring-members 25 tends to maintain said armatures 23 and their locking bolts 24 in their normal positions so as to cause the bolts to engage with said lock-disk or wheel 10 in the locking relation herein-above described.

, Secured in a suitable position adjacent to said pay-as-you-enter door or turn-stile is a coin-receiving device adapted to receive a coin and thereupon cause the operation of the mechanism for releasing said door or turn-stile from its locked or immovable condition. Said coin-receiving device com prises a suitable casing 27 provided with a coin-chute 30 which delivers a coin to 'a circuit-closing mechanism which is arranged within said casing 27, the same being constructed and operated as follows :Secured to the inner side of said casing 27, and suitably insulated thereupon, is a bracket-member 40 which is provided in its free end with 'a coin-receiving space or cut-out portion 41,

the same being presented in a proper position so as to register beneath the outletmouth or end 42 of said coin-chute 30. Secured upon the opposite and interior side of the said casing 27, and in alineinent with said bracket-member 40, is a solenoid-coil 43.

Supported upon a partition-memben 44, within said casing 27 so as to be located opposite the free end of said solenoid-coil 43, are a pair of standards 45, provided with bearing-portions comprising sets of rollerbearings 46 for slidably supporting an armature 47. The outer end of said armature 47 is provided with an enlarged portion 48 having in its free end a coin-receiving space or cut-out portion 49 which registers opposite said coin-receiving space or cut-out portion 41 of said bracketnember 40, and beneath the outlet-mouth or end 42 of said coin-chute 30. The said respective coin-receiving spaces or cut-out portions 41 and 49, and the respective members in which they are formed, are electrically and physically separated from each other, but the former are designed to conjointly receive a proper coin after the same is delivered by the extension 33 of the coin-chute 30. Arranged about said armature 47 between one of said standards 45 and the free end of said solenoid-coil 43, is a spring-member 50 which bears at one of-its ends against the free end of said solenoid-coil 43, and at its other end against a suitable stop secured to said armature, such as the transverse pin 51. The tension or pressure of said spring-member 50 tends to maintain said armature 47 and its coin-receiving portion in its normal position, ready for the reception of a coin.

To release the door or turn-stile locking mechanism, a coin of proper denomination is deposited in the mouth of said coin-chute 30, whereupon the coin is delivered to the respective receiving spaces or cut-out portions 41 and 49 of the bracket member 40 and said enlarged portion 48 of the armature 47. The coin thus received straddles said bracket-member 40 and said enlarged portion 48, bridging over the intervening space between said parts, which closes or completes an electrical circuit, whereby the electric current is caused to pass from a battery 52, or other suitable source of electrical energy, through the conductor 53, to one of said standards 45, whence it passes into the armature 47 and its enlarged portion 48, through the coin and into said bracket-member 40, from which the current enters a conductor 54 leading to a terminal of one of said solenoid-coils 20. Said solenoidcoils 20 are connected in series by the conductor ceiving grooves or spaces 11 of the lock-disk or wheel 10, thus permitting said pay-asyou-enter door or turn-stile to be revolved, and the person seeking entrance therethrough may pass. As soon as the door or turn-stile is revolved by the ingoing person, the said lock-disk or wheel 10 is also revolved, whereby said bolt-receiving grooves or spaces 11, from which said locking bolts 24 have been withdrawn, are carried beyond the line of movement of said locking bolts 24, and the circumferential surface of said lock disk or wheel 10 is presented in said line of movement of said locking-bolts. At the same time, this revolving movement of the lock-disk or wheel 10 carries around a contact-block 57, which is one of a plurality of similar contact blocks suitably secured upon the under side of the lock-disk or wheel 10, said contact-blocks 57 corresponding in number to the number of said boltreceiving grooves or spaces 11, and each of the same being arranged in proper location with relation to one of said bolt-receiving grooves or spaces. The said contact-block 57 operates to close a secondary electrical circuit, by being brought in contact with a contact-receiving elementarranged in said circuit. Said contact-receiving element comprises a suitable standard 58, preferably secured upon the floor or bottom of said floor-pit 6, and mounted upon said standard 58 is a pairof spring-contact-receiving members 59, which are suitably insulated from each other and from said standard 58 by means of suitably disposed insulating blocks 60. Each of said contact-receiving members 59 are provided with suitable reta'ining members, preferably, in the form of bolts 61 which are provided with nuts and washers 62, and secured upon the free ends of said bolts 61, in any suitable manner, are binding posts 63. Thesecondary electrical circuit, of which said contact-receiving element is a part, comprises a battery 64, or other suitable source of electrical energy, one pole of said battery being connected by means of a conductor 65 to one of the terminals of the solenoid-coil 43, and the other terminal of said solenoid-coil 43 being connected by means of a conductor 66 to the binding-post 63 of one of the said contact-receiving members 59. The binding post 63 of the other of said contact-receiving members 59 is connected by means of a conductor 67 to the other pole of the battery 64. As said contact-block 57 moves into contact with the respective contact-receiving members 59, the said secondary circuit is completed, by bridging over the current from one contact-receiving member 59 to the other, through said contact-block 57. Said secondary circuit being thus completed, the solenoid-coil 43 is put in operation so that its attractive function is exercised upon said armature 47, and is thereby drawn away from its proximity to said bracket-member 40. This action removes the supporting influence of said enlarged portion 48 from the coin, which thereupon falls. The coin being thus removed the main circuit, in which are the said solenoid coils 20, is interrupted or broken, and the attractive influence of the sameupon the armatures 23 is discontinued, whereby the latter are moved forward by their respective spring-members 25 until the said anti-friction roller 24 of the locking- .bolt 24 brings up against the outer circumferences of said lock-disk or wheel; The continued partial revolution of the door or turn-stile continues the movement of said look-disk or Wheel 10, which carries away from its engagement with said contact-receiving members 59, the said contact-block 57, and thereby breaks or interrupts said secondary circuit,whereby"-the attractive influence of the solenoid-coil 43 upon the armature 47 is discontinued, permitting said spring-member 50 to return the same to its normal initial position, with its coin-receiving portion in proper relation to said bracket-member 40, ready for the reception of another coin. A further partial revolution of said lock-disk or wheel 10 carries into the line of movement of said lockingbolts 24, successive bolt-receiving grooves or spaces 11, into which said locking bolts 24 are projected by the tension or pressure of the respective spring-members 25, thus locking the door or turn-stile against further movement, until another coin is deposited in said coin-controlling device, as will be clearly evident.-

It will thus be clearly apparent, that the present invention presents a, novel construction of locking and releasing mechanism which is automatically operated by means of a coin-receiving device. The passage of a person through the door or turnstile, and the consequent movement of said door or turn-stile, during such passage, operating to reset both the coin-controlled device and the locking elements, through the medium of closing ,a secondary electrical circuit.

The present invention provides a payas-you-enter door or turn-stile adapted to he of great utility, and of such a construction as will permit the same to be used for many purposes; the same being admirably adapted for use, for example, upon surface or other cars, in railway stations, in places of amusement and recreation, and in fact in all places to which entrance is barred except upon the payment of a prescribed fee.

I am aware that changes may be made in the various arrangements and combinations of the devices and parts as well as in the details of the construction of said parts, without departing from the scope of my presentinvention, as set forth in the foregoing specification and as claimed in the clauses of the appended claims. Hence, I do not I limit my invention to the exact arrange- -ments and combinations of the varlous devices and parts and details of construction as described in the foregoing specification, nor as disclosed in the drawings accompanying the same.
